I'd argue that the optimum was in long run to migrate to the standard version, that everyone (e.g. new employees) know. Replacing the usually particular (or even weird) way implemented own flavour.

I know, I know, long run does not exists in today's investor dominated scenarios. Code modernization is a fairytale. So far I seen no exception in my limited set of experiences (but with various codebases going back to the early 90's with patchy upgrades here and there, looking like and old coat fixed many many times with diverse size of patches of various materials and colour).
